Abstract

La presente invención proporciona de manera general lentes oftálmicos multifocales, por ejemplo, lentes intraoculares multifocales, que emplean una región refractiva central para proporcionar una potencia de enfoque refractiva y una región difractiva para proporcionar dos potencias de enfoque difractivas. En muchos casos, la potencia de enfoque refractiva proporcionada por la región central de los lentes corresponde a una potencia de enfoque lejano que es sustancialmente igual a una de las potencias de enfoque difractivas mientras que la otra potencia difractiva corresponde a una potencia de enfoque cercana. Como tal, en muchos casos, las propiedades de enfoque de los lentes están dominadas por la capacidad de enfoque lejano, especialmente para ltamaños pequeños de pupila.
